Dust from Type-Gases and the Likefo which the followinp is a specification.

This invention re a p tracting dust from type cases and the like 'in which the type case is placedin a closed casing and subjected to the action of a'blast of air while being agitated, to shake the type or the like, the dust laden air being drawn off by a. suction fan, and has for its object to simplify the'construction ofsuch; I without.

apparatus, to agitate the t w ole case t0 intervals over the whole surface thus msuring a more thorou h blow dust-,.and to prevent t e dust'la en air from being discharged into the atmosphere. f

My invention comprises inner and outer closed chambers a'rran ed in a closed. stem containing a fan or b ower, an air d1strib" liter, and a filter. If desired'external' air inlets may be provided to the system.

My. invention also com rises im roved" agitating mechanism where y a circu ar cillating and jogging motion is obtained which throws the type fromfs'ide to side. i

In the preferred form'of myiin'vention I'- employ a single blower, fan or bellows for blowing and exhauszing, and connect the same' to a wind chamber, i inthe bottom of which chamber nozzlesare so need as to blow down on to the type case 'out the dust-whichjis drawn to the back and ends of the ap a'ratus through a filter to W the suction of t e-blower, fan 'or bellows.

The type case is supported in a tray to which a circular motion is given rand-also a jogging motion as hereinafter .describiul which agitates the whole of the typ'eiat the same time, but avoiding severe hammering or .poundin .of the type case I 1 v odification' the chamber is divided into two air tight compartments byahorh zontal diaphragm. Two. sets of nozzles conthe chamber, said nozzles terr'ninating im nected to thetwo compartments are. dis

inediately above the type caselsurface. One I compartment of the chamber and therefore one setgof the nozzles, is connected to the discharge "01 a blower or bellows, the other being-connected throu moves the'dnst from t to the inlet of the blower or bellows. v the blower is in operation one set of nozzles blows on to the-agitated ty case,*a'nd the his by the other passes through the filter. 1n the filter, the'-" air is Leaving the dust drawn through thefbl'owerand used again 1n the sam'efway. Thus all dust-Y is taken; and deposited in th 1 1 the [type case filter.

A jogging motion is also imparted to the tray by four small rollersj and a ball g. This mechanism is shown in lan in. Fig. 8. In the top oithe'tray balls g are mounted in sockets, and allow the type case to move slightly in a horizontal plane, as shown in Figs. 1 and 7.

In the modification shown in Figs. 4, 5 and 6 the space above the diaphragm eis again divided into two chambers upper and lower, by a diaphragm 2 and nozzles a lead from the 11 per chamber tothe luider side of the diap rag n e. vThe lower cham-- her is connected to the delivery of, the

blower, and the upper to the suctionthrough.

the filter d. Thus the dust laden an is led from the whole area of the type case insuring that allthe dust is extracted.

Small air outlets and inlets h may be provided in the outer casing 11 if desired.

In the modified form of construction shown in Figs. 9, 10 and. 11 the perforated diaphragm is replaced by anumber of perforated or slotted tubes l rotated at the same speed and in the same direction from the blower spindle in slotted sleeves la. The

tubes l are open at one end into awchest- In connected with the delivery-of the blower b, and the perforations e are so arranged angularly that they are uncovered successively from right to left in the drawings and the slots in the sleeves k are of such a size that each tube blows for about i; ofa revolution. Thus there is a continuous sweeping action toward the vertical passage down to the filter.

What I claim and desire ters Patent is 1. In apparatus for extracting the dust from type cases and other receptacles, in combination, a casing, a second casingpositioned within said first casing, said second casing being smaller than said first casing,

whereby a space is provided between the casings ada ted to receive a receptacle, a blower within said second casing, means for leading the air from said blower to the receptacle, and a filter interposed in one of the walls of said second casing, whereby the air may pass therethrough and return to the blower within the second casing after having the dust removed therefrom.
